Each of these bits is packed in a separate plastic case. They are good for their price. Remember, these aren't $50 beats. You get what you pay for. I needed a few 1/4 round bits for my WiFi router just to route in areas where my large PC router was difficult to fit in and grinding was too time consuming. These beats do their job. The bearings were tight but not too tight with no play. My only gripe is that the shim behind the bearings is too big and slightly cut into the tree in places. A bit of hand sanding with 220 grit for 30 seconds didn't fix anything, but was still annoying. Otherwise good beats.
